Definitions

  • the present invention relates generally to milling tools and, more particularly, to milling tools in which cutting inserts are secured to a toolholder by a clamping screw,
  • a typical technique of securing the inserts in pockets formed on the toolholder body is via a screw that extends through a hole in the insert and into a threaded hole in the toolholder body.
  • the screw has an enlarged head that clamps against a surface in the hole in the insert to clamp the insert in place.
  • the enlarged head usually includes a key grip, typically a female key grip, that can be driven by a male tightening (or removal) tool or "key". For various reasons, it may be difficult or impossible to access the key grip on the clamping screw with the male tool.
  • flutes in the toolholder may be configured so that there is insufficient clearance space for a tool to enter the key grip on the insert.
  • JP 61 175313 U on which the preamble of claim 1 is based, discloses a milling tool having a clamping screw easily accessible from the chip space of an adjacent milling insert.
  • DE 30 21 355 A1 discloses a milling tool having a clamping screw with key grips at its ends.
  • the milling tool includes a toolholder having an insert-receiving pocket, a cutting insert having a hole provided therein, the cutting insert being disposed in the pocket, and wherein a clamping screw has a male key grip at a first end and zero or more key grips at a second end, the clamping screw extending through the hole in the cutting insert into a threaded hole in the toolholder so that threads on the clamping screw mate with threads in the threaded hole, said male key grip being remote from the cutting insert, the second end of the clamping screw comprising an enlarged head comprising a clamping surface that abuts a clamping surface in the hole of the cutting insert.
  • FIG. 1 is a perspective view of a milling tool according to an embodiment of the present invention
  • FIGS. 2A-2C are schematic, cross-sectional views of another milling tool according to an embodiment of the present invention.
  • FIGS. 3A-3D are perspective, side, top, and bottom views of a clamping screw according to an embodiment of the present invention.
  • FIGS. 4A-4C are perspective, side, top, and bottom views of a clamping screw according to another embodiment of the present invention.
  • FIG. 1 A milling tool 21 according to an aspect of the present invention is shown in FIG. 1 .
  • the milling tool 21 comprises a toolholder 23 having an insert-receiving pocket 25.
  • the milling tool 21 further comprises a cutting insert 27 having a hole 29 provided therein.
  • the hole 29 may extend substantially centrally through the insert 27 as seen in FIGS. 1 and 2A-2C , or may be disposed off-center, such as at an edge of the insert.
  • the cutting insert 27 can be manufactured from directly pressed cemented carbide.
  • cemented carbide is here meant WC, TiC, TaC, NbC, etc., in sintered combination with a binder metal such as, for instance, Co or Ni.
  • the cutting insert is preferably at least partly coated with layers of, e.g., Al 2 O 3 , TiN and/or TiCN. In certain cases, it may be justified that the cutting edges consist of soldered superhard materials such as CBN or PCD.
  • a clamping screw 31 is provided having a male key grip 33 at a first end 35 and, ordinarily, a key grip 37, ordinarily but not necessarily a female key grip, at a second end 39. Further references to the key grip 37 will refer to it as a female key grip, it being understood that the key grip need not be a female key grip.
  • the female key grip 37 at the second end 39 can be omitted, if desired, so that there is only a male key grip 33 at the first end 35 of the clamping screw 31. While not illustrated, it will be appreciated that more than one key grip can be provided at either end of the clamping screw, such as by providing a male key grip around circumference of the end into which a female key grip extends.
  • key grip it is intended to refer to male and female fastener components that are adapted to be driven by a specially adapted tool typically referred to as a "key”, however, it will be understood that other types of tools not specially adapted for use with the particular milling tool or clamping screw might be usable, as well.
  • the clamping screw 31 extends through the hole 29 in the cutting insert 27 into a threaded hole 41 in the toolholder 23 so that threads 43 on the clamping screw mate with threads 45 in the threaded hole.
  • the second end 39 of the clamping screw 31 comprises an enlarged head 47 comprising a clamping surface 49 that abuts a clamping surface 51 in the hole 29 of the cutting insert 27 when the clamping screw is fully installed, as seen in FIG. 2A .
  • the insert 27 can be indexable to a plurality of different positions to facilitate use of multiple cutting edges on the insert.
  • the toolholder comprises a plurality of insert-receiving pockets
  • the milling tool comprises a corresponding plurality of cutting inserts and clamping screws.
  • the threaded hole 41 in the toolholder 23 may connect the pocket 25 with an enlarged hole 53 extending to an external surface 55 of the toolholder or the hole 41 may extend all the way to the external surface 55.
  • the first end 35 of the clamping screw 31 can be disposed in the enlarged hole 53 so that the male key grip 33 is remote from the cutting insert 27.
  • the enlarged hole 53 is of sufficient size to permit a tool 57A (shown in phantom in FIG. 2B ) including a female key grip 59a adapted to mate with the male key grip 33 at the first end 35 of the clamping screw 31 to mate with the male key grip and turn the clamping screw.
  • the external surface 55 of the toolholder 23 to which the enlarged hole 53 extends may be, as seen in FIG. 1 , a surface of an enlarged recessed area or flute 61 of the toolholder.
  • the enlarged hole 53 will typically be in one leg 63 of the flute 61 and will typically face a pocket 25 for another insert 27 on another leg 65 of the flute
  • the insert 27 can be mounted relative to the toolholder 23 such that a working cutting edge 67 of the insert forms an angle ⁇ relative to an axis R of rotation of the toolholder.
  • the insert's cutting edge 67 forms a so-called axial angle ⁇ with the axis R of rotation that can be between 0 °-45°, preferably between 15 °-20°.
  • the angle ⁇ is ordinarily positive, but can be negative.
  • the male key grip 33 can be sized so that it is receivable in the female key grip 37, such as where the male key grip is a same type of key grip as the female key grip so that the male key grip and the female key grip are adapted to mate with female key grips and male key grips, respectively, on other, identical clamping screws 31.
  • the male key grip 133 may, alternatively, be a different type of key grip than the female key grip 137 as seen in the clamping screw 131 shown in FIGS. 4A-4D showing a "TORX" type female key grip and a hexagonal male key grip. While the male key grip 133 shown is too large to be received in the female key grip 137, the male key grip can be smaller in other embodiments so that it can be received in the female key grip.
  • a largest cross-sectional dimension of the male key grip 33 or 133 is no larger than a smallest cross-sectional dimension of the threads 45 in the threaded hole 41 in the toolholder 23 so that the male key grip is adapted to pass through the threaded hole, and ordinarily no larger than a smallest cross-sectional dimension of the threads 43 on the clamping screw.
  • the clamping screw 31 or 131 can comprise a neck portion 69 or 169 between the threads and the male key grip. The neck portion 69 or 169 may be useful to provide a longer clamping screw without necessarily making the threads 43 or the male key grip 33 or 133 longer.
  • the illustrated neck 69 is smaller in diameter than the threads 43 and the male key grips 33 or 133, but it may be larger in diameter than the male key grips, as long as it is sufficiently small to be able to pass through the threaded hole 41 in the toolholder 23. While the present application primarily discusses embodiments of a clamping screw 31 having male and female key grips of the same type, it will be appreciated that such a clamping screw can ordinarily be replaced with a clamping screw 131 having male and female key grips of different types, except as otherwise indicated herein.
  • the toolholder 23 and the clamping screw 31 may be configured such that at least one of the male key grip 33 and the female key grip 37 is inaccessible by a tool adapted to mate with the at least one of the male key grip and the female key grip during at least part of an installation or a removal of the clamping screw.
  • the toolholder 23 and the clamping screw 31 may be configured such that the female key grip 37 is inaccessible by a tool adapted to mate with the female key grip during at least part of an installation or a removal of the clamping screw and such that the male key grip 33 is inaccessible by a tool adapted to mate with the male key grip during at least a different part of the installation or the removal of the clamping screw.
  • the male key grip is accessible by a tool 57A.
  • the tool 57A can be used to drive the clamping screw from the beginning of the installation ( FIG. 2B ) until the tool 57A can no longer be used and the tool 57B can be used to finish installation (to the position shown in FIG. 2A ) or, during removal, when the tool 57B can no longer be used, the tool 57A can be used until the screw is in a position to be removed, as seen in FIG. 2C .
